///**
// * Provides convenience methods for in-app billing. You can create one instance of this
// * class for your application and use it to process in-app billing operations.
// * It provides synchronous (blocking) and asynchronous (non-blocking) methods for
// * many common in-app billing operations, as well as automatic signature
// * verification.
// *
// * After instantiating, you must perform setup in order to start using the object.
// * To perform setup, call the {@link #startSetup} method and provide a listener;
// * that listener will be notified when setup is complete, after which (and not before)
// * you may call other methods.
// *
// * After setup is complete, you will typically want to request an inventory of owned
// * items and subscriptions. See {@link #queryInventory}, {@link #queryInventoryAsync}
// * and related methods.
// *
// * When you are done with this object, don't forget to call {@link #dispose}
// * to ensure proper cleanup. This object holds a binding to the in-app billing
// * service, which will leak unless you dispose of it correctly. If you created
// * the object on an Activity's onCreate method, then the recommended
// * place to dispose of it is the Activity's onDestroy method.
// *
// * A note about threading: When using this object from a background thread, you may
// * call the blocking versions of methods; when using from a UI thread, call
// * only the asynchronous versions and handle the results via callbacks.
// * Also, notice that you can only call one asynchronous operation at a time;
// * attempting to start a second asynchronous operation while the first one
// * has not yet completed will result in an exception being thrown.
